Dual polarization is achieved by putting a rectangular or circular patch in between two orthogonal gaps. At the beginning a single-polarized patch is considered. Then by using anequivalent circuit, the impedance matching property of the gap is being configured. After optimization of the length of the patch and width of the gap, a dual polarized antenna is being considered. Here in this article we projected a new technique to design dual polarized microstrip antenna for WLAN, WiMAX, wireless applications using circular patch. By combining all resonant modes we have finally achieved a wide operating bandwidth. Experimental result of the projected antenna shows the operating bandwidth of 21.56% (5.24–6.37 GHz) for (differential mode S-parameter) S dd11 ≤ −10 dB with a high port isolation of 40 dB and a relative gain of 13.5 dBi is achieved. From the result analysis this antenna finds its applications for various WLAN and Wi-MAX frequency band.

用于 WLAN 和 WiMAX 应用的紧凑型宽带双极化天线的设计和性能分析

双极化是通过在两个正交间隙之间放置一个矩形或圆形贴片来实现的。开始时考虑单极化贴片。然后通过等效电路,配置间隙的阻抗匹配特性。在优化贴片长度和间隙宽度后,正在考虑双极化天线。在本文中,我们提出了一种新技术来设计用于 WLAN、WiMAX、使用圆形贴片的无线应用的双极化微带天线。通过结合所有谐振模式,我们最终实现了宽工作带宽。投影天线的实验结果表明(差模 S 参数)的工作带宽为 21.56%(5.24–6.37 GHz)小号 dd11≤ −10 dB,具有 40 dB 的高端口隔离和 13.5 dBi 的相对增益。通过结果分析,该天线适用于各种 WLAN 和 Wi-MAX 频段。
